Specification of Letters Patent.

Application filed October 28, 1908. Serial No. 459,815.

To all whom it may concern:

Be it known that I, JULIUS A. PERKINS, a citizen of the United States of America, and residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Roller-Bearings, of which the fol lowing is a specification, such as will enable those skilled in the art to which it appertains'to make and use the same.

This invention relates to anti-friction bearings for the journals of axles, shafts, and the like, with particular reference to roller bearings, and 1s an improvement over the form of construction shown and described in United States Patent, No. 664,822, issued to meon the 215th day of December, 1900.

One object of the present invention is to provide solid rollers, instead of hollow ones provided with spindles, thereby increasing the strength of the bearings and decreasing the space occupied thereby.

Another object is to provide means whereby the rollers may move radially of the journal axis, at either end thereof.

Another object is to provide acarrier or cage which maintains the rollers in corresponding axial planes of the said journal.

Another object is to provide bearing blocks at the ends of the rollers for supporting and guiding the said rollers in their planetary movement, said bearing blocks being attached to and portable with the rollers.

Another object is to provide a separable cage which can be assembled in the operative position on the journal. f

Another objectis to provide locking means for the cage members which prevent movement thereof, one upon the other, when my roller bearing is assembled; and still another ob ect is to provide means whereby the cageis always held in. a position concentric with thejournal.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters'in each of the views, and in which Figure 1 is a side elevation of the cage which I employ,

showing one roller in potional, view of one of the roller ends I vided with my self-contained bearing-block; and Fig. 4; is a similar view of a m0difica-' tion of the construction shown in Fig. 3.

' application, I have f sition, and partly in section; Fig. 2 is a secfon taken on the line 22 of Fig. 1, with a fragmentary showing of the journal and raceway for the rollers, and a lock for the cage members; Fig. 3 is a fragmentary, secpro- In the drawings forming a part of this showna portion of the ournal aof an axle, shaft, or the like,- and at b is shown a portion of the roller raceway, between which, and said journal, are mounted a plurality of cylindrical bar sections, forming solid rollers c, the ends of which are mounted in bearing blocks d, car ried by a cage 6.

In the form of construction shown in Figs. 1 and 2 I provide the said rollers with tapered journals 0 which are inserted into correspondingly recessed anti-friction rings a, similarly tapered to fit into tapered recesses in the blocks d, as shown at d.

The cage 6 is preferably composed of two segmental members 6 and 6 joined at e, in the axial plane of the journal, by means of a locking plate 6 which consists of two members of greater width than at the intersect-ion thereof, the members e and 6 being provided with similarly shaped recesses which register with each other. Each of the cage members e and 6 consists of a semi-annular plate a at each end of the cage, joined by means of ribs or cross bars 0 either integral therewith or connected thereto in any desired manner, these ribs being equidistant from each other and forming roller spaces 6 and at the ends of the said spaces, in the plates of, are radial block guiding recesses 6 which are of less transverse diameter than the roller spaces, whereby parallel shoulders are formed, as clearly shown.

As shown in Fig. 2, I the plates c with a stop f, in the position of each of the guiding recesses e and which serve to limit the movement of the bearing blocks 0., thus maintaining the cage in a position concentric with the journal a, when the bearing is assembled.

In assembling my roller hearing, I place the rollers in position in each cage member Patented Sept. 5, 1911. i

provide one edge of separately, omittingthe two rollers in the positions of'the joints 6*, the latter being placed in position after the said members have been joined by the lock. therefor and,

7 when these' last named rollers are placed in. position, it will be seen that lateral movement'of the cage members is prevented and a positive lock results.

a It will thus. beseen that I provide .a roller bearing employing solid rollers, and permit movement thereof radially of the journal, it

being understood that the bearing blocks are freely, but not loosely, movable in their guidingrecesses,'thusinsuring the automatic adf justment of' the" rollers to imperfections and irregularities in the journal .a, and I also; provide aroller bearing cage which,

while' composed of separable 'members, is

: in position from readily assembled and, be members thereof ":positively locked agaist individual move- "men. 1 l-. The locking plate 6 shown in Figs. 1 and .2, is'preferably provided with a flangeE resting in ,a'correspondingly shaped recess in the members '6 and 6 being thus pre- "vented from falling or frombeing forced 'out when'the'cage is assembledwith the rollers therein, the said plates being placed within the cage members, as'clearly, shown; In .Fig.. 3" ofthe'drawings I have shown "one form. of bearing block attachment wherein the" block dis provided with a groove d, andthe journal with agroove both of which: grooves, jointly, engage a ring 0 therebetween',-- thus. forming a flexible, de-

.'ta'chable, connection which permits rotation ofthe journal within the block. I In Fig. 4 I have shown a modification of thefconst'ruction. just described in that I mount a boss d upon the block d, said boss extending intoacorresponding recess in the 4s lar to those last described, but it will be tcrs Patent, is

rollerend, the attaching means being simi-.

apparent that many other methods for attaching the blocks to the rollers may be designed and be equally as operative, this hearing block construction 'being applicable "to bearings designed for use in heavy machineryand the like, wherein the rollers are supported by the-said bearing blocks, as well as guided in their planetary movement. Having fully described my invention, what I claim as new and desire to secure by Let 1.

A cage, for use inroller bearings, comprising separable, segmenital, members, means for lOCkll'l said members a amst transverseseparatipn, rollers carried by said cage and provide with tapered journals, bearing blocks for said rollers carried by said cage,

and tapered rings of anti-friction material mounted upon said journals and in said bearing blocks, said rollers, blocks and rings preventing longitudinal separation of said members.
